Problem with FTP transfers :(

Post by Firestorm ZERO »

Ok here's my problem.

When I transfer files via FTP sometimes they get corrupted (Despite the transfer in FTP progs say complete). Other times not.

This occurs on *ONLY* FTP transfers , both local (within my LAN) and online (with my friend). HTTP transfers (with+without download spliting) and those P2P downloads/uploads have no corruption.

Here is what I use...
P4 2.26 GHz w 512 MB ram
Windows 2000 SP4
WS_FTP Pro v8.0
Serv-U v4.1
Zonealarm Pro v4.5.530.000
Using Cat 5e cables connected to a router (SMC 7004BR)

I always have to send a MD5 or a SFV file to check for the corruption. I wonder what is causing it? The software is pretty up-to-date. The router maybe old but why does the corruption *only* occur in FTP transfer is weird :/

are you using the correct transfer mode ascii vs. binary?

My FTP prog (WS_FTP) is set in Auto-Mode. So when I transfer files to my friend's FTP, all files are transfered in binary unless they are in ASCII file extention list. The files I transfer are mainly movies (avi, mpg) and archives (rar, zip) which are not in the ASCII list.

I assume my friend is also using auto-mode in his FTP prog when he transfer files to my FTP.

Anyway "auto-mode" is set by default on FTP programs aren't they?

Which direction do the corruptions occur? Transferring up to friend and he receices corrupt file OR transfer down and youi receive corrupt file?

If either of you have DSL then you usually must ftp transfer in passive mode.

To determine if the client is at fault, do a transfer using IE browser by connectiong to any ftp port like so. Put in IE address bar:

ftp://username : password @ domain.com

(with NO spaces between letters, spaces added here to avert smily icons)

To specify the port used then follow:
domain.com: port# or
ip followed by port#
xxx.xxx.xxx.xxx:1234
No one has any right to force data on you
and command you to believe it or else.
If it is not true for you, it isn't true.

Both ways. When I upload to him and when he uploads to me. Like I said only sometimes they come corrupted not always.

We both use PASV.

Ok. I'll try that.
